Hi Don, The same is true on IA64, if you look at the configure script there's a little hack of mine... if test "$HaveLibGmp" = "NO"; then if test "$HostArch_CPP" = "ia64"; then AC_MSG_ERROR([You need to install libgmp (the in-tree version does not work on IA64).]) fi; fi; It's probably broken for 64-bit architectures in general.

Hey all,
Some mips64 and gmp observations:
The normal way, unregisterised, with the in-tree gmp, v3.1.1:

43 tests, involving floats or double, passed with the external libgmp. The brokeness exhibited itself as segfaults, or showing values as 0.0 or 0.0e0 instead of the correct result.
These tests that were cured by using an external gmp:
arr0{05,06,13,16} num0{01,07,08,11} cg0{14,18,19,24,26,28,34,35,42} arith0{01,04,06-08,12-14,16-17}

So mips64 users should definitely use the external gmp provided with Irix, as it must be better configured than ours for the time being.
And, I guess all porters should take note that even though a port builds, and can then rebuild ghc itself, it may still be broken in ways only the testsuite will find.
